DAVID W. CLARKE, OF TIDIOUTE, PENNSYLVANIA.

NECK YOKE.

.ZTPECIFICATIQN forming part of Letters Patent No. 331,376, dated December 1, 18.85.

Application filed April 7, 1885.

To all whom, it may concern:

Be it known that I, DAVID W. CLARKE, a citizen of the United States of America, residing at Tidioute, in the county of IVarren and State of Pennsylvania, have invented certain new and useful Improvements in Neck- Yokes, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure 1 represents a plan of a yoke constructed according to my invention, with one of the end pieces removed. Fig. 2 shows an end view of the same; Fig. 8, a transverse vertical section; Figs. 4, 5, and 6, details of two of the parts, and Fig. 7 is a modification.

The invention relates to the construction of the yoke and its fittings; and it consists in the peculiar combinations and the construction and arrangement of parts hereinafter more fully described and claimed.

A. represents the yoke, which is preferably made in two parts, as indicated in dotted lines in Fig. 1, .and is provided with a clamp-tube, B, at the center, each end of which clamp ca-rrics an open ring, 0, of the form'shown in Fig. 4. These rings are formed, by casting or otherwise, preferably open and in the form shown in Fig. 5, to allow of the pole-ring D being inserted. After the insertion of the polering the ends 0 are brought together, as shown by dotted lines in Fig. 5, and inserted between the jaws of the clamp. Bolts E are then put through the holes in the clamp and the open rings and nuts F screwed on them, which, when screwed home, securely fastens the elamptube to the yoke and holds the open rings in place. By this means the two halves of the yoke are not only strongly fastened together, but the pole-ring is held in a very secure manner.

If the yoke is made in one piece, in lieu of a single broad clamp two narrow ones or rings may be used, as shown in Fig. 7. here the tube-clamp is employed I may use a single open ring in the center, as shown in dotted lines; but I prefer two, as shown in full lines. I generally make the hole for the bolt in the ends a after they are brought together; but it may be done at any time to suit the convenience of the maker. The end clamps, G, are of somewhat similar form; but the open rings Serial No. 161,449. (No model.)

H are different, as shown by Fig. 6, which represents the ring in an open state in full lines and closed in dotted lines, as it is when in position. This open ring is secured in the clamp by two bolts and nuts, as shown. By this construction and arrangement a strong and durable neck-yoke is provided at a Very moderatecost, and short pieces of lumber may be utilized that could not be usefully employed otherwise, and, moreover, if one end should get mashed or damaged,it could be replaced at half the expense it would cost to renew the entire yoke.

WVhere the yoke is made in two pieces it will be observed that the clamp-tube performs the double function of uniting the two halves of'the yoke together and as a means of securing the pole-ring to the yoke.

I am aware of the Patent No. 157,849, and make no claim to anything shown therein, for I consider my invention as essentially difierent from the device there shown and claimed.

What I claim as new is 1. The combination, with a yoke formed of two pieces, of a clamp'tube embracing and securely holding in a fixed position said two pieces, a ring embraced between the jaws of said clamp, and a bolt passing through said clamp and ring, substantially as described.

2. The combination,with a yoke,of aclamp tube surrounding said yoke, a ring having an open joint, with both ends substantially close together and held between both jaws of the clamp, a ring inserted in said open-jointed ring, and a bolt binding directly on said clamptube and passing through it and part of the open ring, substantially as described.

3. The combination, with a yoke, of a clamptube surrounding said yoke, a closed ring, an open ring having both its ends held between both jaws of the clamp, and fastening means acting directly on the clamp and passing through part of the open ring, substantially as described.

In testimony whereof I aflix my signature, in presence of two witnesses, this 26th day of March, 1885.
